Oh, and I'm on a Mac too. The only problem I've had is uploading routes from the 705 to mapmyride.com. Can't get it to work.

I haven't even tried uploading a route from the 705 to MotionBased. Works fine with the Forerunner 301, though.

And, if you're using Windows software under Parallels, at least with my old Parallels 2.x, getting the 705 to talk to the computer is a two-step process. The 605/705 is a USB mass storage device, so it communicates with the computer differently than the earlier models. I have to connect the 705, tell Parallels 2.x to recognize it, then disconnect it and re-connect it again. Never had to do that with the Forerunner 301. And since that's the only USB device I've used with Parallels, I don't know if that's a common problem.

Edit: Just uploaded today's ride from the 705 to MotionBased, no problem.
